    The highest temperatures - ‘HEATSHIELD’

    • Outstanding sealing ability for prolonged exposure to the highest possible temperatures and aggressive aerospace fluid environments, those are the key requirements for FFKM materials supplied to the aviation industry for engine sealing applications.

      3M™ Dyneon™ Perfluoroelastomer PFE 7301BZ has, for many years, proven to meet the demands of the aerospace market for high temperature sealing solutions.

      More recently, the development of E-21464 HeatShield demonstrates even further enhancement of the already outstanding long term, high temperature (316 °C) compression set resistance of PFE 7301BZ HeatShield and takes the performance of our high temperature FFKM materials to an even higher level and ready to serve the next generation of high temperature jet engine applications.


    Typically, FFKM materials provide the best possible resistance to very high temperatures and extreme chemical environments, whilst maintaining their elastomeric sealing capabilities and without compromising their key mechanical properties, such as compression set resistance, volume swell resistance and tensile properties.

      Why use FFKM?

      • In the aerospace, chemical processing and semiconductor industries, production process and operating temperatures are steadily increasing and chemical & plasma environments are becoming more and more aggressive.

      • FFKM seals are the material of choice for chemical transportation in harsh environments where safety must not be compromised.

      • FFKM materials from Dyneon are developed from unique combinations of polymer and curative technologies, enabling us to provide sealing solutions that meet the demands of these very challenging market sectors.

    The best all round high temperature and aggressive chemical resistant material in one solution - ‘CHEMSHIELD’

    • New challenges in the Chemical Processing Industry demand ever improved productivity and reliability from sealing solutions.

      The newly developed 3M™ Dyneon™ Perfluoroelastomer PFE 7502BZ combines the superior chemical resistance capability of a peroxide curable FFKM with enhanced high temperature performance (275 °C) and provides more reliable sealing capability by comparison to other conventional Perfluoroelastomer grades in the marketplace.

      PFE 7502BZ ChemShield helps to extend the lifetime of a sealing solution, to prolong the periods between routine maintenance and to reduce the risk of unplanned downtime and environmental issues.

      Sealing solutions based on the latest Perfluoroelastomers from Dyneon help to reduce overall costs and facilitate improved safety and increased productivity in chemical production plants.
